RESUMEN

Se conoce que la síntesis de los factores de nodulación por bacterias del género Rhizobium se induce por diferentes compuestos de naturaleza flavonoide que son exudados por la planta leguminosa. En este trabajo se estudia la capacidad de diferentes compuestos de actuar como inductores de los genes de nodulación en tres cepas de Bradyrhizobium japonicum y se compara el efecto cuando se emplean dos concentraciones del inductor. Se presentan los perfiles de factores Nod sintetizados por las diferentes cepas ante cada inductor. El número de estructuras diferentes sintetizadas y su concentración dependen del tipo de inductor, de su concentración y de la cepa empleada.
